Description
Technical field
The present invention relates to a kind of absorbent structure for car headlamp, belong to car headlamp technical field.
Background technology
In modern car light manufacturing industry, design, manufacture, technique is all increasingly sophisticated, use a large amount of advanced technology, car light quality is day by day perfect.But automobile lamp operationally, can amount of heat be produced and form water vapour after light source is lit, can condense at the inner surface of lens of car light cover again after steam chance in lamp body in air is cold, especially for headlamp, due to depositing of knot mist phenomenon, the mist pearl that knot mist is formed is one of main source of car light internal water accumulation, and car light internal water accumulation, can again become knot mist again, so the safety of circuit in the service life of serious threat vehicle light bulb and car light, not only affect car light outward appearance, and the illuminating effect of car light is had a greatly reduced quality, affect traffic safety.Water vapour in addition in car light can cause car light material corrosion in the long-term condensation of lamp reflector and lens surface, accelerated material is aging, make a series of consequences such as car light material deformation, optics regulating effect are destroyed, if heat can not be processed timely and effectively, service life and the performance of surrounding components can be affected.Therefore at present automobile lamp especially headlight tool all can adopt the radiating mode of different structure, but all there is radiator structure complexity, the problem that cost is high.But up to the present, car light knot mist remains and affects car light quality subject matter.
Summary of the invention
The object of this invention is to provide a kind of structure simple, cost is low, namely can not affect its illumination functions, can improve again the absorbent structure for car headlamp of the knot mist phenomenon of car light inside.
The present invention is the technical scheme achieved the above object: a kind of absorbent structure for car headlamp, comprise lamp body, it is characterized in that: the back cover hole place of described lamp body is provided with bonnet and cover plate, described bonnet comprises the clamping ring be made up of rubber and the lid be made of plastics with ring limit, upper surface, lid ring limit projection annular convex rib crimping clamping ring cannelure in and be fixedly connected with clamping ring, the back cover hole of clamping ring and lamp body is tightly connected, and is provided with at least two projections in lid; Described cover plate is tubular, and the projection clamping on cover plate on plural notch and lid, drier is placed in the cavity between cover plate and lid, and lid is provided with the ventilating groove hole of interruption.
Wherein: described cover plate is provided with plural raised line along its periphery, the notch on each raised line and the projection clamping on lid.
Described cover plate side is provided with stopper slot, and lid is provided with corresponding limit rib, in the stopper slot on the cover board of the limit rib clamping on lid.
The ring limit of described lid is also provided with spacing ring, and spacing ring connects with the end face of clamping ring.
Of the present invention car light bonnet to be improved, this bonnet adopts the clamping ring that rubber is made and the lid with ring limit be made of plastics, bonnet is arranged in the back cover hole of car light, keep sealing by the back cover hole of clamping ring and car light, and lid and lid clamping, therefore drier can be placed in the cavity between cover plate and lid, and by lid ventilating groove hole, make the steam in the drier absorption car light in lid, to reduce the steam in lamp body, namely reduce knot mist phenomenon.The present invention only needs the bonnet place after lamp to increase drier, without the need to improving headlamp inside, structure is simple, manufacturing cost and use cost is low, namely the illumination functions of headlamp can not be affected, the knot mist phenomenon of car light inside can be improved again, reduce fog to the impact of the safety of circuit in car light service life and car light.Lid of the present invention and cover plate adopt interface arrangment, convenient installation and replacing drier.
